Sushi Express Nanshijiao

Was seated along the counter close to the entrance and staff room - staff walking behind me constantly grazed, knocked on my back with their "flailing" arms (I counted 4 times) seemingly exercising little to no effort to avoid it. The supervisor did nothing to advise or reprimand the staff. Oh BTW, there were plenty of empty seats further inside of the restaurant, did not know why I wasn't seated there. The conveyor belt had nothing of interest to most patrons, for some odd reasons only the less sought after sushi dishes were put up. I presume they are trying to market the less popular dishes but knowing that if I did order them and the dishes would probably come from those circulating on the conveyor for the longest of time, I would definitely refrain from doing so. "Last but not least", the salmon did not taste fresh. Disappointing if not infuriating experience.
